Two people reading each other’s mind could lead to feedback problem. I don’t know if people do this anymore, but when I was young and two people disagreed on what they should do, they sometimes decided by each displaying one finger or two, with one person winning if the total number of fingers was even and the other winning if the total was odd. Imagine two mind readers doing this. They would each keep changing their mind based on what the other person was thinking. What a mess!
